guest cisco OS VLAN TAGGING removed by bridge

[Rgehin]

Hi,
I'm installing a cisco virtualized router on proxmox. As network setting, i set up a bridge interface. But, when i made do1q encapsulation in my cisco virtualized router (so in the guest os), i noticed that at the output bridge interface, the tag has been removed.
I spent several hours on the internet looking for people in the same context... without success....
does anyone have an idea? is it possible to tag from a guest OS?

thanks for reply
